Q.10:- How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line?
For x number of resistors of resistance 176 Ω,
Here Supply voltage, V = 220 V
Current, I = 5 A
Equivalent resistance of the combination = R, given as
∴four resistors of 176 Ω are required to draw the given amount of current.
